Common Sense Institute Arizona Belief Statement

We believe sound fiscal and economic research is essential to uphold Arizona’s economic vitality, future, and individual opportunity. 



CSI Arizona’s mission is to examine the fiscal impacts of policies, initiatives, and proposed laws so that residents are educated and informed on issues impacting their lives. Common Sense Institute was founded in 2010 originally as Common Sense Policy Roundtable in Colorado. CSI’s founders were a concerned group of business and community leaders who observed that divisive partisanship was overwhelming policymaking and believed that sound economic analysis could help residents make fact-based and common sense decisions.
